In the wilds of the Local Group, a lonely galaxy stays set apart
Latest Science News -- ScienceDaily - Hace 11 horas
This scene, captured by ESO's OmegaCAM on the VLT Survey Telescope, shows a lonely galaxy known as Wolf-Lundmark-Melotte, or WLM for short. Although considered part of our Local Group of dozens of galaxies, WLM stands alone at the group's outer edges as one of its most remote members. In fact, the galaxy is so small and secluded that it may never have interacted with any other Local Group galaxy -- or perhaps even any other galaxy in the history of the Universe.
Cellular "blindness" to chromosome cohesion defects
Phys.org - latest science and technology news stories - Hace 11 horas
Research led by Raquel Oliveira, group leader at Instituto Gulbenkian de Ciência (IGC; Portugal), has elucidated how cells are almost blind to chromosome cohesion defects. The results, published in the scientific journal Cell Reports uncovered how these defects, often associated with cancer development, congenital diseases and infertility, evade the strict surveillance of the checkpoint mechanisms that ensure faithful genome segregation.

DNA molecules directly interact with each other based on sequence
Phys.org - latest science and technology news stories - Hace 11 horas
Proteins play a large role in DNA regulation, but a new study finds that DNA molecules directly interact with one another in a way that's dependent on the sequence of the DNA and epigenetic factors. This could have implications for how DNA is organized in the cell and even how genes are regulated in different cell types, the researchers say.
Cellular 'light switch' analysed using neutron scattering
Phys.org - latest science and technology news stories - Hace 11 horas
The internal movements of proteins can be important for their functionality; researchers are discovering more and more examples of this. Now, with the aid of neutron spectroscopy, dynamic processes have also been detected in so-called "LOV photoreceptors" by scientists from Jülich, Aachen, Dusseldorf and Garching near Munich. These proteins are widely distributed throughout nature and are of biotechnological relevance. The results highlight the immense potential of neutron scattering experiments for the analysis of cellular processes. The research has recently been published in the ... más »
Blurred lines: Human sex chromosome swapping occurs more often than previously thought
Phys.org - latest science and technology news stories - Hace 11 horas
It turns out that the rigid "line in the sand" over which the human sex chromosomes—-the Y and X—- go to avoid crossing over is a bit blurrier than previously thought. Contrary to the current scientific consensus, Arizona State University assistant professor Melissa Wilson Sayres has led a research team that has shown that X and Y DNA swapping may occur much more often. And this promiscuous swapping, may in turn, aid in our understanding of human history and diversity, health and disease, as well as blur rigid chromosomal interpretations of sexual identity.

Reconstructing the cell surface in a test tube
Phys.org - latest science and technology news stories - Hace 11 horas
Like the phenomena of flocking birds and shoaling fish, the dance of molecules across a cell's surface has long fascinated theorists, physicists and biologists alike. Unlike bird and fish behaviour, however, cell surface dynamics cannot be observed and studied easily. However, it is important to understand these processes as they are crucial for cells to gain information about their environment and respond. So how does one understand the rules that govern movement of molecules across this arena? By reconstructing the cell surface from scratch, perhaps? Now, scientists from the Natio...más »

The damaging effects of black carbon
Phys.org - latest science and technology news stories - Hace 11 horas
Air pollution, both outdoors and indoors, causes millions of premature deaths each year. The deaths are mainly caused by the inhalation of particulate matter. Black carbon, a component of particulate matter, is especially dangerous to human health because of its tiny size. But black carbon not only has impacts on human health, it also affects visibility, harms ecosystems, reduces agricultural productivity and exacerbates global warming.
Ancient Pluto may have had lakes and rivers of nitrogen

The New Horizons probe revealed the surface features of Pluto in rich detail when it reached the dwarf planet in July 2015. Some of the features look like snapshots of rivers and lakes that are locked firmly in place by Pluto's frigid temperatures. But now scientists studying the data coming back from New Horizons think that those frozen lakes and rivers could once have been liquid nitrogen.

Brussel·les: víctimes, llibertats restringides, estigmatització

1. De nou el debat sobre les fotos de les víctimes en portades. Una de les imatges més repetides mostra un parell de noies atordides, amb ferides que semblen lleus, però tot i així amb sang a la cara i les mans. Apareix a la primera pàgina de 'La Vanguardia', 'El Punt Avui', 'The Times' o 'The Guardian'. Al meu parer, és una opció legítima –els diaris hem de poder mostrar– però també discutible: les dues protagonistes es trobaven en un moment massa vulnerable com per poder decidir si volien ser exposades al món.

High-intensity 'sprint training' may be gaining popularity at gyms, but if you're new to this form of exercise, the workout could do more harm than good. A study has found signs of stress in the muscle tissues of their non-athlete, untrained subjects after ultra-intense leg and arm cycling exercises. Perhaps more concerning, researchers reported the untrained subjects had a weakened ability to fight off free radicals, molecules that can alter DNA and harm healthy cells.

(Phys.org)—It's strange to think that there was a time when molecular cell biology was considered by professionals of other scientific specialties as disreputable or laughable. But the motivation for much cellular biology research around the mid-20th century was the search for the mechanisms of aging and the means to alter them—for centuries, people have been understandably frustrated by the indignities of aging and the burden of mortality, and the search for a "fountain of youth" was universally regarded as a foolish and hopeless endeavor.

A team of engineers headed by Prof Dr Cemal Esen from the Applied Laser Technologies lab at the Ruhr-Universität Bochum develop microscopic components and assemble them to larger objects with the aid of laser tweezers. They are thus establishing methods that one day may be utilised to manufacture machines in dimensions of a few micrometres. The group has successfully tested several fastening techniques. At present, the researchers are experimenting with doped materials which can be used for rendering objects magnetic or giving them electrically conductive properties.
